My MATLAB gets sluggish over time so I have to keep restarting it

My MATLAB gets sluggish over time so I have to keep restarting it. I think that when I'm running a heavy script quite a few times my computer's memory is not getting properly freed up after each one. Does anyone else get this?

What operating system are you using?

[Tom]

Sorry - I missed that question. I'm using OS X Snow Leopard 10.6.8.

Answer 1

[Image Analyst]

If you're calling image or imshow a bunch of times that can slow things down, so call "cla reset" right before to clear out old images.

Answer 2

[douglas]

maybe write

clear all 
close all
clc

at the beginning of your script to ensure you dont have a ton of variables or figures open in the background.

Where is Jan's clear-all rant when you need it?

[Daniel Shub]

In this case clear all might be a valid answer. Better would be to figure out what is slowing things down, in the absence of that clear all is a nice hammer.

No, I do not get this. I will point back to one of the first questions I asked on Answers: href=""<http://www.mathworks.com/matlabcentral/answers/1093-how-do-i-reset-matlab-to-its-launched-state</a>>
